hello freinds

it’s not possible
is it impossible in all MK versions ?

thank you normis
You can only block by file extension, not redirect to another proxy. Here is full list of features in Proxy:

thank you again normis , but i know how to block the files extention,
even im using the dstnat , not using redirect 
i tryed to do this rule..
add action=dst-nat chain=dstnat comment=Network2 content=.exe.zip*.rar*.zip
disabled=no dst-port=80 in-interface=!Internet protocol=tcp to-addresses=
84.22.44.55 to-ports=8088
but as u said , it seems its not possible
NAT happens on the first packet of a connection.
The first packet of a download over TCP is just a SYN to establish the connection. There is no indication of what the connection will carry. By the time you are able to determine that a zip file or executable file download is taking place it is already too late to NAT.
if you redirect to proxy, then you could try to do something when you detect that content is some file or something. but that is long shot.
i used the redirect , but in this case i only can drop the files extention but not redirect to another ,
